燃機関の排気微粒子捕集装置。 In an exhaust particulate collection device for an internal combustion engine, which collects particulates contained in the exhaust gas by filtering the exhaust gas from the engine using a ceramic filter, an upstream exhaust passage extending from the engine and the atmosphere are connected to each other. A case interposed between the open downstream exhaust passage, a pair of cylindrical inner and outer filters housed concentrically inside the case, and a pair of inner and outer cylindrical filters closely engaged with the end faces of these filters, respectively. a pair of partition plates for positioning and engaging both filters in the case; an inlet provided in one of the partition plates for communicating the space between the two filters with the upstream exhaust passage; An internal combustion engine comprising a cavity formed on the inner periphery of the filter and an outlet provided on the other partition plate for communicating the cavity formed on the outer periphery of the outer filter with the downstream exhaust passage. Exhaust particulate collection device.
